quick poll, does anyone actually have QoS working with the latest FW? I've managed to get it working ONCE - then after a reboot it stopped. Do I have a faulty product, or is this an issue others have come across (from viewing the forums it appears not).

Fixed it: http://support.draytek.net.au/index.php?/Knowledgebase/Article/View/478/6/how-qos-setting-affects-internet-network-speeds

I reduced the speed to 75% - QoS works now.
